RAPID Linked geomorphic-ecological disturbance response as a driver of alterations in aquatic-to-terrestrial energy flux: consequences of dam removal on a mid-size river

拆坝为研究河流对环境扰动的反应提供了一个极好的机会。尽管拆坝作为河流恢复方法越来越受欢迎，但许多生态系统的反应在很大程度上仍然未知。这个快速项目将调查大坝拆除对河道地貌和碳和能源从水流向陆地的短期（1.5年）反应的影响。为此，将在俄亥俄州哥伦布的一条中型河流中研究水生-陆生食物网，那里最近拆除了一座大型低头水坝。研究小组在大坝拆除前三年收集了研究系统中的数据，因此能够很好地进行这项研究。水坝拆除对水生-陆地连接、食物网和河岸生态系统群落的地貌影响代表了新的研究，该研究建立在水坝拆除后鱼类和其他水生生物群的记录群落变化基础上。建议的工作的智力价值在于建立大坝拆除的干扰如何驱动链接的河流河岸responses.By推进我们的理解大坝拆除对生态系统功能的干扰的短期影响，这项研究将有助于努力维护和/或恢复河流在人类主导的环境。该项目包括本科生和研究生的参与，并将研究结果纳入俄亥俄州州立大学（OSU）的课程。此外，当地高中学生传统上没有接触到研究和干活动将通过现有的合作伙伴关系与俄勒冈州立大学的向上绑定计划从事项目研究活动。研究小组还将提供一个大坝拆除研讨会运行了俄勒冈州立大学的希尔迈尔奥伦坦吉河湿地研究公园。该研讨会将讨论大坝拆除的生态后果，并将涉及公众，当地流域团体，城市规划者和机构人员。

Dam removal provides an excellent opportunity to study how rivers respond to environmental disturbance. Despite the increasing popularity of dam removal as a river restoration approach, many ecosystem responses remain largely unknown. This RAPID project will investigate the influences of dam removal on short-term (1.5 years) responses in channel geomorphology and aquatic- to-terrestrial flows of carbon and energy. To do this, linked aquatic-terrestrial food webs will be studied in a mid-size river in Columbus, OH, where a large, lowhead dam was recently removed. The study team is well positioned to conduct this research, having collected data in the study system three years prior to dam removal. The geomorphic influence of dam removal on aquatic-terrestrial connections, food webs, and riparian ecosystem communities represents novel research that builds on documented community shifts in fish and other aquatic biota following dam removal. The intellectual merit of the proposed work lies in establishing how the disturbance of dam removal drives linked river-riparian responses.By advancing our understanding of the short-term effects of the disturbance of dam removal on ecosystem function, this study will contribute to efforts to maintain and/or restore rivers in human-dominated environments. The project includes involvement of undergraduate and graduate students and inclusion of study findings in The Ohio State University (OSU) coursework. Additionally, local high school students not traditionally exposed to research and STEM activities will be engaged in project research activities through an existing partnership with OSU's Upward Bound program. The study team will also deliver a dam-removal workshop run out of OSU's Shiermeier Olentangy River Wetland Research Park. This workshop will address ecological consequences of dam removal and will involve the public, local watershed groups, city planners, and agency personnel.
